Forced Vibration of S.D.O.F System
Observation 1: Effect of time period on maximum response
- Run the experiment with default ground motion and building parameters
- Observe the response and note down the maximum response.
- Repeat the experiment by changing the values of mass of the structure. (Note: Change in mass will change the time period of the structure)
- Note the maximum response.
- Plot the graph between the maximum response and the time period of the structure.
Observation 2: Effect of resonance without damping
- Select Resonance from the list of earthquakes. And set damping to Zero
- Run the experiment and note the displacement.
- Response value increases and reaches peak when forcing frequency is nearing natural frequency of the structure.
- Draw the plot between maximum response and frequency ratio.
